Application. filed October 2, `1909. Serial No. 520,665.

To all whom 'it l17mg/ amr-ern Be it known that Storm itl. CHASE, of Syracuse, in the county oi" )nondaga and .Qtateol' New York, have invented a certain new and useful ldotor Land implement, ot' which the followingl is a siiecilication.

My iniention has for its object the produc tion of a motor land roller suitable to be used as a roller only, or in connection with other implements, as mowers, etc.,` and it consists in the combinations and constructionsI hereinafter set Yforth and-claimed.

ln describing this invention reference. is had to the accompanying `drawing in which like characters designate corresponding parts in all the views.

Figures 1 and 2 are, resiiiectively, perspective and plan views of my land roller. Fig. 3 is a sectional View on line Afr-1, Fig.

2. FF il is a fragmentary View, partly in section. 'llustrating the connection between the fork for the steering roller and the contiguous part of the `trame.

This motor land roller ei'auprises, generally, a frame, di ne rollers, a steering roller, and a motor. lireierably the driving rollers are arranged in axial alinement and with their opposing ends spaced apart, and the steering roller is disposed in t'ront of the space between the ends of the driving rollers, and the motor is supported by the 'frame bctweeu the ends ol said driving rollers.'

As here shown the traine comprises main elements or bars l. (usually two in number) extending between the driving rollersl 2, and ha ving forward extensions :il which rise over the steering roller Ll, the bars 1 being provided with bearings 'For the opposing ends of the axles 5 of the rollers 2: andsaul tranne also comprises elements (i extending laterallyA from the rear portions ot' the bars l and Lnclosing the driving rollersy 2, these elements being provided with bearings for the outer ends of the axlesy 5 ol? the driving rollers 2.

a '.lhc traine also comprises a sillitable fork T carriedby the forward extensions I?) o'l the main bars l. this fork straddling the steering roller thereof.

`front or :1nd supporting the laxle 'lnhe motor or engine 9 is supported by the main bars 1 of the frame between the driv- 'ing rollers 2, and the crank shaft 10 thereof extends crosswise of the axes of the rollers 2 and connected to a transmission gearing located within a suitable case 11. This gearing is connected by a shaft 12 to a powertransmitting element comprising a suitable differential gearing located within a case 13, and shafts 14. which are arranged in axial alineinent, are journaled in bearings 1.5 at the rear of the axles 'for the driving rollers 2 and 'extend parallel to such axles.

The bearings 15 are mounted on the vtrame bars 1, are preferably adjustable lengthwise of such bars by screws 1G, Fig. 2 and 3, and are secured in their adjusted position by clamping bolts 17. yThese shafts 14 are connected at their inner ends to gears of the differential gearing and carry at their outer ends pulleys or sprocket wheels 18 which are connected by belts or sprocket chains 19 to pulleys or sprocket Wheels 20 mounted on the inner or opposing ends of the axles 5, the belts or chains 19 extending forwardly from the pulleys or sprocket wheels 18 at opposite sides ot the motor and between the outer sides of the main bars l. and the inner ends of the driving rollers 2.

The lork 7 is suitably connected to the front end of the extensions 3 oi the main bars 1, being here shown, Fig. 4, as provided with an upright stud or pivot 21 loosely fitting in an opening 22 in a plate 23 fixed to the extensions 3, and as also provided with a convex bearing surface 24 aty the base of the piv'ot 21 for engaging the underlace of the plate 23. Thus the fork 7 can su ivel or turn about. the axis of the pivot 21 and can also more to a limited extent at an angle to its pivotal movement, permitting the axlefor thetcering roller to tilt out of a horizontal plane when said roller is passing over uneven ground.

A suitable sector or track is supported by the fork and is arranged concentric with the axis of the pivot tal plane ot' the axle ot the steering roller 4. The ends of a suitable cable 26 are con- 21 and in the horizon` portion of the sector or traclr"` .facilitates the forward movement of the f operator.

nected to the opposite ends of the sector or track 25 by adjustable links' or bolts 27, this cable26 extending around an' idler 28 carried by the frame and around a pulley 29 on the lowerend of a steering post 30 which is supported by thel frame in front of one of the driving .rollers v A seat 3l "for .the operator is preferably supported over the driving roller 2 at the rear ofthe steering post 30. 1

An antifriction member or roller 32 ena gages the rear surface of the intermediate and lthus steering roller and steadies the same during the swiveling of the fork 7. Said roller 32 is carried by a suitable bracket 33 fixed to a cross piece 34 extending between the main bars l.

My land roller is here shown as supporting a lawn mower 35 which is located directly inl front of one 2,v and beneath the steering post 30 and the seat 31. Said mower is suitably suspended from one of the 'frame elements '6 and is shiftable toward and from the ground bya lever 2G arranged vnear the seat 3l. The mower includes the usual rotating l ife 37 preferably actuated by the motor 9. As here shown a shaft 38 extends in front of, and

parallel to, the driving roller 2 farthest from the mower 35 and is provided at its opposite ends with pulleys or sprocket wheels 39, 40, one 39 being connected by a belt or chain lite a pulley or sprocketvwheel mounted on theshaft for the knife 37, andl the other 4:0 being connected by a belt or chain 42 to a pulley or sprocket wheel 43 mounted on the outer end of the axle for said driving roller 2 and within the contiguous frame element 6. Obviously, any other suitable power-transmitting means may be substituted for the various sprocket wheels and chains.

A land roller constructed as described is particularly strong and durable, is 'adapted for use on hilly or level ground, is easily controlled, and isparticularly durable and elicient when used in connection with an implement, as a mower, since said mower is arranged infront of one of the driving rollers' and 'directly under 'the -eye of the Owing to the illustrated and described ar- 'rangement of the moweror, implement and ofthe actuating mechanism'for the mower y y knife or other movable element of an implement, the dragging resistance on one side of the machine due to 'the location of the implement is substantially offset by the driving of the mower knife 'from the axle of the roller on the other side of the ma chine, the vlocation of the implement and anceon oppositesides of the of the driving rollers mieder -the actuating mechanism for its movable element substantially equalizing the resistdilferential gearing.
